ALIYUN::DTS::Instance - Resource Orchestration Service

ALIYUN::DTS::Instance is a new resource type that is used to create a Data Transmission Service (DTS) instance.

Note

We recommend that you use new resource types to replace previous resource types that are used to create DTS resources. The following information shows the correspondence between the previous and new resource types:

ALIYUN::DTS::MigrationJob (previous): ALIYUN::DTS::MigrationJob2 (new) and ALIYUN::DTS::Instance (new)

ALIYUN::DTS::SynchronizationJob (previous): ALIYUN::DTS::SynchronizationJob2 (new) and ALIYUN::DTS::Instance (new)

ALIYUN::DTS::SubscriptionInstance (previous): ALIYUN::DTS::SubscriptionJob2 (new) and ALIYUN::DTS::Instance (new)
